Introduite par Parker en 1961, la méthode des impulsions d'énergie (méthode Flash) est la technique la plus utilisée et la plus connue pour déterminer la diffusivité thermique des matériaux céramiques. Elle consiste en une méthode directe de détermination de la diffusivité thermique, dans laquelle une impulsion de courte durée d'énergie rayonnante est focalisée sur l'une des faces de l'échantillon, et la variation de température sur la face opposée est mesurée. Cette étude vise à décrire explicitement le chemin adopté par Parker pour l'élaboration de cette méthode. En partant de l'équation de diffusion thermique, on obtient la solution de l'équation différentielle partielle avec des conditions aux limites non homogènes, ce qui fournit la
Introducido por Parker en 1961, el método de pulso de energía (Método Flash) es la técnica más utilizada y mejor conocida para determinar la difusividad térmica de los materiales cerámicos. Consiste en un método directo para determinar la difusividad térmica, en el que se enfoca un pulso de corta duración de energía radiante en una de las caras de la muestra, y se mide la variación de temperatura en la cara opuesta. Este estudio tiene como objetivo describir explícitamente el camino adoptado por Parker para la elaboración de este método. A partir de la ecuación de difusión de calor, se obtiene la solución de la ecuación diferencial parcial con condiciones de límite no homogéneas, que proporciona la

Introduced by Parker in 1961, the energy pulse method (Flash Method) is the most used and best known technique for determining the thermal diffusivity of ceramic materials. It consists of a direct method in determining the thermal diffusivity, in which a short-lived pulse of radiant energy is focused on one of the faces of the sample, and the temperature variation on the opposite face is measured. This study aims to explicitly describe the path adopted by Parker for the elaboration of this method. Starting from the heat diffusion equation, the solution of the partial differential equation with non-homogeneous boundary conditions is obtained, which provides the
طريقة نبض الطاقة (طريقة الوميض) التي قدمها باركر في عام 1961 هي التقنية الأكثر استخدامًا والأكثر شهرة لتحديد الانتشار الحراري للمواد الخزفية. وهي تتكون من طريقة مباشرة في تحديد الانتشار الحراري، حيث يتم تركيز نبضة قصيرة العمر من الطاقة الإشعاعية على أحد وجوه العينة، ويتم قياس تباين درجة الحرارة على الوجه الآخر. تهدف هذه الدراسة إلى وصف المسار الذي اعتمده باركر صراحةً لوضع هذه الطريقة. بدءًا من معادلة الانتشار الحراري، يتم الحصول على حل المعادلة التفاضلية الجزئية بشروط حدودية غير متجانسة، والتي توفر
